Monday was a vacation day

August 6, 2008

Those who know me will understand why the following is a typical vacation day for me…

At last the much anticipated day arrived and my new shop building, along with my neighbor Rick’s, arrived on the tractor trailer.   As our lots connect, it was expedient to unload at his site, and I’ll subsequently ferry my materials over once we have them sorted out.   After waiting all day for a planned, 1pm delivery, the trucker finally arrived at about 6 pm and we set up our crane truck alongside and started unloading.   More than half way through the process, we remembered the camera and snapped a few pics.

We rigged the pieces for hoisting using the 6 foot long, red painted load distribution beam and 10,000 pound sling straps.   The girders and bundles of stamped channel were fairly easy, while the heavy lifts turned out the be the stacked bundles of siding and roof sheeting. These stacks of sheeting easily weighted several thousand pounds.

Luckly, extra help showed up to work on the ground, guiding the pieces as the crane placed them in somewhat orderly stacks.

I don’t do this everyday, and there are little planning details that become evident once something like this gets underway.  For example, placement of the crane truck to maximize reach and lifting capacity.  The trailer was 48 feet , and while the crane has a 46 foot 3 stage boom, the use of the full length de-rates the lifting capacity, as does the reduction in boom angle.    When deployed closer to the horizontal, the reach is increased, but so is the radius of the load and the tendancy to tip.

During a near maximum lift over the rear of the truck, I found one of the front wheels lifted clear of the ground, and  it was definitely time to put things on hold while I deployed the rear outriggers.

After several hours,  the truck was empty, our clothes were drenched from working in the heat, and we had many piles distributed all around the crane which look like this.

I plan to take more pics and blog the assembly process highlights, maybe even post some video to youtube.
